ATTACI-LMENT FOR SHOE HEELS.

Application filed December 5, 1921. Serial No. 520,084.

I To all whom it may concern:

Be it known that I, FELIX R. CHAUDET, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Attachments for Shoe Heels, of which the following is a specification.

My invention has relation to improvements in shoe-heel attachments, and consists in the novel features of construction more fully set forth in the specification and pointed out in the claims.

The objectof the present invention is to provide a resilient attachment for shoe-heels comprising a disk of soft rubber that is free to rotate on the heel. A further object is to provide a shoe-heel attachment that will hug the heel closely entirely around its periphery; and one that is initially formed slightly dish-shaped, and is flattened on being secured to the shoe-heel. Further and other advantages will be better apparent from a detailed description of the invention in connection with the accompanying drawings, in which Fig. 1 is a side elevational view showing my improved attachment secured to a shoe, part of the attachment being shown in section; Fig. 2 is an enlarged bottom plan of the attachment and reinforcement plate therefor; Fig. 3 is a middle transverse section through the heel attachment; Fig. 4 is a side elevation of the reinforcement plate; Fig. 5 is a face view of the blank after the holes have been punched in it.

Referring to the drawings, S represents a shoe, the heel H of which has secured to it my improved resilient attachment A by means of a central screw 1. The attachment A comprises a body 2 of resilient material (preferably rubber) said body 2 having a reinforcement plate 3 molded into it. The body 2 is molded slightly concavo-convex or dish-shaped, and the reinforcement plate 3 is located adjacent the face a on the concave side. The plate 3 is pressed with a central coutersunk portion I), at the center of which is an opening 0 to receive the screw 1 and has an annular channel 0 formed near its periphery. The outer edge I) of the countersink 7) extends slightly beyond the face a. After the plate 3 is molded into the body of rubber 2 the outer surface of the channel 0 lies in the same plane'with the face a. An annular wedge-shaped slit d is provided in the convex side of the body 2 at the intersection of face 6 with inclined face 6' opposite the intersection of face a with inclined face a, the angle of divergence of the sides of the slit (Z being substantially equal to the complement w of the angle formed by the face a with the face a. A series of openings m are formed in the plate between the channel 0 and countersink b, and a series of openings 1, n are formed in the respective sides of the channel 0 so that when the plate 3 is molded into the body 2 the material composing said body may flow through these openings and bind the plate firmly in the body of rubber 2. The body 2 is also provided with an opening 0 in line with opening 0 in the plate to receive the screw 1. It will be observed that the openings m, n, and

n are in staggered relation, i. e., no two adjacent openings are in line, so that there will be no tendency for the plate to cree in the body 2. The presence of the channe 0 also minimizes the tendency of the plate 3 to creep. When the attachment A is secured to the shoe-heel H and the screw 1 driven home the body 2 will gradually be flattened out against'the heel and conse- -quently will hug the heel very snugly around the perlphery owing to the pressure of the surface 42; against the heel. However, this pressure is not sufficient to prevent the attachment A from rotating about the screw 1 since the friction of the surface a is relieved by the outer face of the channel 0 of the plate 3 which also bears against the heel. In fact, it may be desirable to mold the body 2 and plate 3 together so that the surface a will be slightly below the outer face of the channel 0.

After the attachment A has been screwed tightly to the heel, the slits d will have been closed and the attachment pressed flat to the shape of a disk. However, if desired, the angle of the slit all may be formed slightly greater than the angle a: so that after the attachment has been affixed to the shoe-heel it will present an annular recess to the ground which gives to the disk anti-slipping properties.

The attachment will also be held against lateral displacement on the heel by virtue of the projecting edge 5 of the countersink b which bites into the heel as the screw 1 is driven home.

Having described my invention, I claim:

1. .An attachment for shoe-heels consisting of a body of resilient material, the margins of said body being turned upwardly, a reinforcement plate molded into said body adjacent its'upper surface within the upwardly turned margins, saidbody being provided with an annular slit at the base of said margins and in its lower surface, and means for securing the attachment to a shoe-heel, said lOOdy flattening to a disk and the aforesaid slit closing when the attachment is in place on a heel.

2; An attachment for shoe-heelsconsisting of a body'of resilient material of circular outline, a reinforcement plate molded into said bodyadjacent its upper surface, the center of said plate being counter-sunk beyond the upper surface of said body, said plate being provided with an annular channel, the outer face of which lies in the same plane as the upper surface of said body, and means passing through the countersink in the plate for revolubly securing said attachment to a shoe-heel so that the outer face of said channel may be free to rotate against the heel, the projecting edge of the counter sink biting into the heel and holding the attachment against lateral displacement.
